 /*
- * All my error handling is done with my error_exit() routine.  It
- * prints an error message to stderr, then does an exit() or abort().
- * It does *not* return to its caller.  It's declared to return an
- *  int , however, so it may be easily used in conditional expressions

+ * expressions like
  *	foo = bar_ok ? baz(bar) : error_exit(...);
